Documents:FBI press release | Criminal complaint When terror suspect Sohiel Omar Kabir arrived in California last week, he had a broken bone in his face, cuts on his head and was suffering from memory loss, according to his attorney.

That attorney, Jeffrey Aaron, is now questioning authorities' handling of Kabir during his capture in Afghanistan and during the two weeks Kabir was held by the military before being turned over to the FBI.

"We think a lot of the injuries occurred during his arrest," Aaron said." "We're investigating what happened and why he wasn't hospitalized."

Federal prosecutors say Kabir, a naturalized American citizen, masterminded a plot to murder Americans abroad and to aid terrorist organizations. They have charged Kabir and three other local men in federal court.

All four defendants have pleaded not guilty.

While the other three suspects were arrested in Chino, Kabir was apprehended in Kabul, Afghanistan.

U.S. Army Special Operations Command officials said that Special Forces teams conducted a military operation known as a "snatch and grab" under the cover of darkness to take Kabir into custody on Nov.17.

The military held Kabir for as long as two weeks, turning him over to the FBI on Dec. 1 or Dec. 2, according to FBI spokeswoman Laura Eimiller.

Eimiller said Kabir's injuries were combat-related and that he was treated by U.S. military medical personnel and cleared to travel back to the United States to stand trial.

Kabir appeared in federal court in Riverside on Tuesday.

"He has staples in his head, a broken facial bone, a very long cut on his face and suffers from memory loss," Aaron said. "Also, his vision is agitated with intermittent flashes of lights and he has difficulty maintaining his balance."

Flashing lights and loss of balance could be symptoms of a severe concussion, which could last for days, weeks or even longer, according to the Mayo Clinic's website.

Aaron declined to say what his client had told him regarding his injuries.

Neither Eimiller nor military officials would provide further information as to the cause of Kabir's injuries.

"All I can share is that Kabir was captured Nov. 17 in an area of Kabul by a combined U.S.-Afghan force," said Lt. Col. Laurel Devine, Army public affairs officer.

The military conducts "snatch-and-grab" operations to capture high-priority individuals who are considered a threat to national security.

"Kabir was detained under the law of armed conflict, and U.S. military transferred him to FBI custody," Eimiller said. "Kabir was arrested by the FBI pursuant to the warrant and was brought back to the U.S. for prosecution for "providing material support to terrorists."

Eimiller declined further comment.

Aaron said he has requested additional information from the military and the FBI but has not received it yet.

"It's not like state courts," Aaron said. "There is no timeline that prosecutors have to meet to turn over the discovery evidence."

Aaron also challenges the case against his client.

"The allegations against him seem to be based on hearsay statements from the other defendants and an FBI snitch who we know is a convicted felon, and he's been paid a quarter of a million dollars by the U.S. government as an informant," Aaron said.

According to the complaint against Kabir and the three other men, the informant who provided information to investigators has been working with the government for four years and has received $250,000 and immigration benefits in exchange for his assistance. The complaint also notes that the informant has been convicted of drug trafficking.

Judge Oswald Parada in U.S. District Court ordered Kabir, who has not yet faced a grand jury or been indicted, be held without bond and scheduled a detention hearing for Tuesday.

Ralph Deleon, 23, of Ontario, Miguel Alejandro Vidriales Santana, 21, of Upland and Arifeen David Gojali, 21, of Riverside appeared before Parada on Wednesday.

Prosecutors allege the three had been planning for nearly a year to fly to Afghanistan to join al-Qaida, Kabir and the Taliban to carry out terrorist acts.

They had purchased plane tickets and were planning to depart to Afghanistan within a few days of their arrest on Nov. 16, according to a federal indictment.

They are also accused of "providing material support to terrorists."

Parada ordered the three men to return to court Jan. 14 for a pretrial hearing and then Jan. 22 for trial.

He assigned the case to Magistrate Judge Virginia A. Phillips in Riverside.
